chinese led lights

[ali1]

Based off the first couple pics, it look like your old cree fixture had more punch to them than the chinese leds. it just looks far brighter and eye-popping than the chinese fixture... unless the brightness was not turned up on the chinese fixture.

Comments/Review:
Customer service from both of my reps was fantastic, they answered all my questions promptly and tolerated me even though I changed my mind every day. A+ for both of these guys (Ada vacationed near end of discussion, Brian took over)

Product review:
Well packaged, exact spectrum I ordered. Shipped and arrived earlier than ETA even as a custom/new item they designed for me. All units arrived in perfect working condition.

Does Evergrow have a fixture like this? SAme color spectrum? I want moonlight but do NOT want to have to manually dim the fixture to get moonlights. This one has separate power to the moonlights so I can use my RKE+ to control that. So lights are two switches, 1 white/ 1 blue, then one more for moon.
All help is appreciated as my current PC are overheating my tank bad. 83-88!!! Thanks, Ty

OK, so I am buying an used and very establish 120 tank, but want to move to LEDs and want the neat features.

All this debate seems so confusing to me. Can someone just tell me.

What do I need to give Evergreen to get the new lights with the best layout for eventual SPS corals. I've got some color blindness... so more interested what MOST people would like. LOL.

Also for the 48" long tank would two of the new fixtures be enough?

Thanks much.

If I wanted to mimic the below the picture, would I use more ww? I really like this setting because it looks like natural sunlight, but colors are not popping in this tank.

2 fixtures should be fine on a 48" tank, however there is no "best" color combination, its like asking 100 people to agree that one color is their favorite. Just not going to happen, we have begun to come to the conclusion that just mixing Royal Blues and cool whites is not enough color spectrum for the corals to exhibit their best coloration. So we have begun mixing in neutral whites, warm whites, Ultra Violets and maybe some reds/greens. The mix bhazard just ordered appears to be working well, may be a good start.

Yikes! Just de-solder them next time. It takes two seconds and it wont warp or damage the led.

If you want a nice sunlight mixture like that, try to mimic the layout I used. Add in 2 or 3 reds as well, and you will get a really nice high noon 12-14k look at 100% with popping color.

But, I guess that is what I'm asking... I'm having trouble even figuring out in this thread that this "good start" is... Keeping personal taste of pretty colors out of the discussion... what is the current take on the "best" full color spectrum that will the corals happy?

[Slayer311]

Short answer, LEDs are still in their infancy in reefs, there is no "best" full color spectrum, we are doing nothing more than experimenting still.

[WillM]

Scuba, I think this is the "good start" that was referred to (I would add that the 65K and 35K refer to 6500K and 3500K respectively, not 65000K or 35000K):

I'll be adding in reds and cyans to test soon to see if they are needed for better visual appearance. Evergrow doesn't use Cyan so I had to get them elsewhere.

In some ways, this light and ratio looks better than my DIY Cree, and in other ways the DIY Cree looks better. I like them both.

[scubawarm]

Perfect. thanks Will!

i am talking to sunny and gave her the above layout (bhazard451's) but for a d120, there are no moonlights (3 yellow ones), so she suggested i guess to just keep them the 450 on the correct switch. should i switch to red or something or just go with that?

They will be on the blue channel.. so 450 makes sense. I personally think some red should go on the white channel. Its all personal preference.

I have a 60 gallon 22 deep 36 wide, has the D120 that has no optics on it, supposedly 90 degree lens from what Sam told me when I ordered it. It covers great with no loss in the ends of the tank about 8" above the tank.

I am ordering the newer unit soon and was curious if I should stay with just the lens like the D120 or go with an optic lens like the new unit you have. I'm a little confused becasue of the led lens vs the optic lens Evergrow offers.

90 led angle and 90 degree optics should be the same thing. I believe the 90 degree optics will still focus better and provide better PAR. You can always remove them too so its good to get them anyway.

I'm not a fan of Cool Whites, but it should give the look you are trying to achieve.

Thanks, i really appreciate your advice.

Another question, i've a cube of 17". Should i'll request 60° lens or i can go with the default 90°?

Thanks

If you ever want to upgrade, keep 90. Otherwise, 60 degrees will work for you over a 17" cube, as the unit is around 17" itself.

I could not get the picture to post. But bhazard can you look at the led lay out and tell me what you think?

I also realized my lights aren't evenly over my tank, and the fixture is shifted to the right a bit. You can see how the numbers are lower on the left side. Numbers should be higher for everyone else who places lights evenly, and I can't remove the bracket from the wall now.

Tank is a 34 Gallon RSM 130D, 24x20x24 I believe. Definitely 24" long and 24" height. Both lights are at 100%.

IT2040 ~7" above the water (Yes, the middle of the tank hits 800 PAR nearly mid way down) I have no idea which leds are making it so high, but it is accurate.

The numbers are excellent:


The 180W DIY Cree/Luxeon at ~9" above the water is friggin insane however. Surprisingly it doesn't sizzle coral. The middle of the tank is 1000+ PAR!

First let me say that this has been an awesome thread...lots of great information!!

As for my question, it seems Reef Breeders is coming out with a verison of their value light with a controller now. What do you think??

"We have a new light on the way, with a built-in controller and heatsink!! The controller has an LCD touch interface, and allows for 24 data points, the whites/colors, royal blues, and moonlights are all separately programmable. The fixtures are linkable, and come with fully adjustable, and tiltable hanging wires. The exact color combo is as follows: channel 1; 16 7500k cool whites, 2 480nm blues, 2 520nm greens, 2 630nm red, 2 660nm reds, and 4 410-420nm violets. Channel 2; 24 450nm royal blue, Channel 3; 3 480nm blue moonlights. The fixture comes with 90 degree optics, and is set at $299 shipped. We are now taking pre-orders, and will ship them out in 2-3 weeks! It looks like the 120watt bridgelux value fixture, with a controller on the front, and a better hanging kit."

Not my photo...i do not take any credit for it.

Reefbreeders is an Evergrow reseller now. That is actually the new Evergrow light I reviewed. The cool thing about reefbreeders is, they use their own nice custom ratio which is good if you don't want to figure out your own layout, and they will service your lights in the US if needed. Evergrow will service the lights for you too through a US reseller, but if you are weary of ordering direct from the factory in China, Reefbreeders is a nice option.

There are perks from ordering from Evergrow direct too, such as quantity discounts on some lights, being able to choose your own led layout, etc. Choice is up to you, but it is the same light in the end.

[fsu1dolfan]

I guess it makes sense since i liked the evergrow one too LOL. Thanks for the quick response!! I think i am going to go this route...i dig their ratio too.

Thanks again for the help!!

There will be a Cree version of the new model, but it won't be anything like my DIY light. Their Cree version will probably use the older Cree XPG/XPE series at 40x 3W each. You also can't get Violet in Crees yet.

My light uses 36 Cree XT-E, 6 Luxeon ES, and 6 Semileds 420nm with the Crees running around 5 watts each. No fixture on the market even comes close to it.

My DIY is actually the Nova A4 light they sell, but completely converted internally. I made a thread in the DIY section of it being built.

[03sonicstang]

Pulled the Trigger on (3) IT2040.

Thanks bhazard451 for all your input and great information!
